Cast from high-grade A356.0-T6 aluminum alloy, this heavy-duty differential cover adds 0.89 quarts of fluid capacity and features half-inch external cooling fins for enhanced heat management. Built-in windage scrapers ensure precise fluid distribution, reducing heat buildup and minimizing parasitic loss for more efficient power transfer. The vertical external fins also form a strong cross-bracing structure, improving load distribution and impact resistance. Both the fill and drain plugs have powerful, high-temperature-rated neodymium magnets to capture ferrous particles. The fill plug is positioned at the factory level.
